BEN B. LAMPREY AND ALMON G. BUGBEE, OF LAKE VILLAGE, NEWV HAMP- SHIRE, ASSIGNORS TO THE LAMPREY MANUFACTURING COMPANY, OF

SAME PLACE.

FEED-WATER HEATER AND LINING FOR FURNACE-MOUTHS.

SPECIFICATION forming part of Letters Patent No. 388,367, dated August 21, 1888.

Application filed March 5, 1888.

To (all whom it may concern:

Be it known that we, BEN B. LAMPREY and ALMON O. BUGBEE, of Lake Village, in the county of Belknap and State of New Hampshire, have invented certain new and useful Improvementsin Combined Feed-Water Heaters and Linings for Furnace-Mouths, of which the following is a specification.

Our invention has for its object the pro- IO vision of a contrivance which will serve the purpose of a feed-water heater for boilers or of heating water for any other purpose, and also as a lining to and support for the mouth of a furnace.

Our invention will first be described in connection with the accompanying drawings, forming a part of this specification, and then be pointed out in the claim hereto appended.

()f the drawings, Figure 1 is a perspective view of the front and mouth of a furnace having our improvements applied thereto, parts being shown as broken out to better show the construction and arrangement of parts. Fig. 2 is a sectional detail, hereinafter referred to.

The same letters of reference designate the same parts in all of the views.

In carrying out our invention we construct the brick-work a of the front or mouth of the furnace substantially as heretofore, and arrange a series of return-pipes, b, at the sides and top of the mouth of the furnace, which serve as a lining thereto and as a support for the arch or bricking over the top and sides of the mouth, as is clearly shown in Figs. 1 and 2.

The pipes b are adapted to receive water entering, for example, the branch 0, which may be supposed to be connected with a bulk-head, tank, pump, or other source of supply, and

Serial No. 266,223. (No model.)

flowing through the coils or returnsections out through the branch (I, which may be con- 4o nected with the boiler, or a heating apparatus,

or tubs of a dyehouse or wool-washing establishment, or other things or contrivances adapted to receive and utilize hot Water.

There may be as many pipes 1) extending up 5 the sides and over the top of the mouth as de sired. These pipes serve as a support to the bricking of the mouth of the furnace and furnish complete 'n'otectiomwhen the pipes have water flowing through or circulating in them, against the burning of the bricks, and, besides this, afford a means of heating the water for use in the boiler in generating steam, or for other purposes, thus saving the expense of fre quent repairs and effecting an economy in the use of fuel.

Having thus described our invention, what we claim is- The combination, with a furnace and its mouth, of the series of pipes extending along the opposite sides and top of said mouth, and the inlet and outlet pipes connected to the respective ends of saidseries of pipes, substantially as shown and described, whereby water in said pipes is heated and the said mouth is 6 braced or supported, as set forth.

In testimony whereof we have signed our names to this specification, in the presence of two subscribing witnesses, this 29th day of February, 1888.
